Super handy post from Adrian Rosebrock on PyImageSearch.
Today is the second post in our three part series on milking every last bit of performance out of your webcam or Raspberry Pi camera.
Last week we discussed how to:
Increase the FPS rate of our video processing pipeline.
Reduce the affects of I/O latency on standard USB and built-in webcams using threading.
This week we’ll continue to utilize threads to improve the FPS/latency of the Raspberry Pi using both the picamera module and a USB webcam.
As we’ll find out, threading can dramatically decrease our I/O latency, thus substantially increasing the FPS processing rate of our pipeline.
